My apologies, I should have been clearer.

The test case *must* test that you can at least register 32 handlers without
error since POSIX Issue 7 mandates this is the minimum number that must be
supported. This way the test case checks for the minimum.

We don't need to check the maximum. Checking for the maximum is more expensive
than just making sure you can register and call 32 handlers.

Now you've added the need for another test case which should verify that
_SC_ATEXIT_MAX returns -1?

Cheers,
Carlos.
